Implications of bulk causality for holography in AdS

Abstract

Gravitational time delay in asymptotically anti de Sitter spaces has consequences for holographic duality. We argue that the requirement of bulk causality implies that it is not possible for a collection of boundary observers, performing local measurements, to extract information from precursors. Using similar arguments, we derive an integrated weak energy constraint on spacetimes which can admit a holographic dual. © SISSA/ISAS 2004.
